This paper is devoted to the fast solution of interface concentrated finite element equations. The interface concentrated finite element schemes are constructed on the basis of a nonoverlapping domain decomposition where a conforming boundary concentrated finite element approximation is used in every subdomain. Similar to boundary element domain decomposition methods, the total number of unknowns per subdomain behaves like $O((H/h)^{(d-1)})$, where $H$, $h$, and $d$ denote the usual scaling… CONTINUE READING
